There is a simple counterargument that I like to use when having a discussion with a Muslim about this. It consists in one simple question: "Why would it be less logical to believe that the laws don't apply to the Universe than to believe that it don't apply to God?" If everything
in the Universe was "designed", it doesn't mean that the Universe itself was designed.
I do believe that what they apply to their god can logically apply to the Universe as well... If, of course, we are willing to accept that the Universe doesn't have a "creator", which seems logical to me since the Universe is defined as "the set of everything that exists". Considering God is outside the Universe is considering he's outside "everything that exist". Unless we give another definition to "Universe"... I asked several religious people what was their definition of "Universe" since their god is supposed to be outside of it and since they won't admit their god is outside "everything that exists". None of them was able to provide me a definition of what their god created...
And then of course it gets even trickier when thinking about heaven, hell, angels... Would they be inside the Universe (since they are "created"), or would they be outside of it ? If angels are inside the Universe, how can they interract directly with God who is outside of it and how can they be close to his "throne" ? What's the "throne of God" anyway, since the scriptures seem pretty literal about it.... Well my opinion is all the equation is clearer without the monotheistic god
